• Surface area of Rotterdam: 300 km2; of the region: 807 km2
• Population of the city: 615.000; of the
Metropolitan region Rotterdam The Hague: 1.6 million
Sea and safety, flexible floodbarriers for shipping and ecology
Dunes (natural and artificially induced) Dikes
Technical solutions i.e. Floodbarriers riskmanagement
floodbarrieres
Former innersea, now freshwaterreserve
Rivers and safety and relation to Ecosystem services
Upstream waterretention and
freshwaterreserves and one of Europe’s biggest wetland nature reserves
In the city water issues combined with social issues
Future vision Rotterdam Watercity 2035
Rivercity
‘sponge city’
Canalcity
Sponge City, the city as a forest! Waterretention!
Watersquares, storage and good public space
Water living, urban agriculture and good housing
Floating buildings green/water roofs

Underground waterstorage for sewage overflow built in 2010 when excavations for underground carpark took place 10.000 m3 = 2.6 million gallon
A dike, with shops below and a roof garden to link the waterfront to the neighborhood: built in 2012/2013
Using Ecology for cleaning water and a green walkway

Playgrounds, childfriendly city 'woonerf' sidewalks go on for kids, special circulation for cars, public transport and bikes in all suburbs since 1980's designed that kids go first !
Green network provided more walking and
biking, 'biking highways' 1.3 bikes per person
Amsterdam, Delft #1 in model split Copenhagen
Rotterdam 17% Portland 2%
Good public transport at the basis 300 m from every home…and combine it with green, grass!
Densification study: Assessment 30.000 inhabitants + 141 HA green
Ecosystem services increases mainly by introducing a green network
Healthy Life expectancy increased with two years
THERE IS ALREADY A LOT……. BUT MANY
NUMBERS …we should add mapping to this not just 1 number fow an area!
Using standerdized data in a local scalable GIS transilience approach
Detailed data to facilitate fast and flexible, make it scalable !
A map is easier to read than dozens of excell sheets
Diagram easier to read than 100 maps!
USE DATA AS THERMOMETER OF WHAT IS DOING WELL/OR NOT identify what themes are below goals, thresholds
Behind each OF 100
indicator is a GIS map Spiderdiagram set up by:

(WAT, WAAR WAAROM DAAR)
challenges opportunities Coaltions
Goals
Kiezen van projecten en inzet van middelen in een gebied
(gebiedsprogramma's )
actions
Put open, objective data at the table
Facilitate the transition process and stakeholders
Asset based planning
To be used in Transition management
Result: Stakeholder chosen themes
Waterproblems, recreation shortagePossible solution : watergarden,square
Follow up
Use this apprach for every neighborhood
Use it for certain urban typologies so you can see what to do in many cases
Use this as a early warning system per typology….and design with nature!

This years international Architecture Biennale:
'Urban by nature' about the metabolism of the city
In some parts of the world people access to the flows, can make the difference between life and death. In other cities they open the way to well-being.
Dirk Sijmons , 2013, TU Delft
Can we plan Rotterdam as an Urban
Ecosystem with a high Q of life?
